Bromelain in pineapple does harm some protein on cell membrane, but many fruits actually contain plant protease. Eating pineapple hurts more because it also contains some glycosides and serotonin, which will enhance the stimulation of protease, and pineapple can reduce the pH of your mouth. Such a low pH environment is more suitable for bromelain to play a role and make your mouth feel stinging!

It is suggested that you can rinse your mouth immediately after eating to restore the normal pH of your mouth, thus reducing the protease activity and tingling.

(ps: bromelain will not affect your oral health, but people with oral ulcers should eat it carefully! )

By the way, soaking pineapple in salt water at home can't hydrolyze protease or denature it, because the enzyme itself is a kind of protein, and salt can only precipitate protein, but high-concentration salt water can really inactivate protease, but the salt solution used at home is generally low-concentration, so the low-concentration salt solution is also conducive to the preservation of bromelain, and it is easier to destroy the protease in your mouth! But can you still eat pineapple if you want to soak it in high concentration salt water? A salty smell ~?

However, some people will say:

"Ah, although what you said is very reasonable, I really won't prick my mouth with pineapple soaked in salt water ~?"

Is it okay? Here, I have to say again that in addition to protease, there is something called "calcium oxalate needle crystal" in pineapple, which will physically harm your tongue and make you tingle. Salt can dissolve this needle-like crystal, protect your tongue, and at the same time, it can also dissolve the organic acid in pineapple, enhance the sweetness and make the taste better. Moreover, the bromelain content of mature pineapples is less than that of fresh pineapples, so some people just soak in salt water and don't prick their mouths.

Someone here is thinking:

"Ah, that really need not salt bubble, how to get all not line? ? "

Emmm~ ~ Well, I'm usually straightforward. So I cut it and ate it. At most, I gargle ...?

But in theory, there is a solution:

1. You can slice the pineapple. Be careful not to leave small burrs when cutting. This thing stung you in the mouth.

2. Then soaking pineapple in warm water and baking soda can reduce acidity and protease activity. 40 ~ 50 degrees water environment will also reduce protease activity.

3. If you don't trust me, soaking the dissolved needle-like crystals of calcium oxalate in salt water should not cause tingling, right?

(ps: But it feels so troublesome. Of course, I don't understand the world of eating goods? )
